How does Riverside MHP compare with other water systems in Warren County?

By EPA's size categories, Riverside MHP is a very small system (500 people or fewer). Warren County has 219 active public water systems. Its population served is well below the county average of 1,491 people per system, and accounts for less than 0.1% of the 326,592 people reported by systems filed under the county. Across New Jersey, the 3,496 active systems average 2,750 people each. Nationally, the average active community water system reports serving 6,703 people, so Riverside MHP is well below that figure.

What does “community water system” mean?

A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. Homes, apartments and mobile-home parks are served by these. New Jersey has 582 active community water systems, 17% of the state's 3,496 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 3,313 New Jersey systems (95%) list groundwater as their primary source.

Who owns and regulates Riverside MHP?

EPA lists Riverside MHP as privately owned. The NJ state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 177 of the 219 active systems in Warren County (81%) are also privately owned.

Does Riverside MHP have drinking water violations?

Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in October 2024. The violations listed here began between October 2010 and October 2024. By type: 3 reporting, 3 monitoring and reporting, 3 contaminant level above the legal limit, 2 public notice, recordkeeping or other and 1 monitoring. The contaminant or rule involved most often is Revised Total Coliform Rule (4 of them). EPA lists 8 as resolved, 3 as unaddressed and 1 as archived. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
